take a look at the following code
var a = new View();
a = null;
....
class View {
[Code]...
will a be in memory after a = null? Does addEventListener adds a strong refernce?
Here's my question. Suppose I've written some AS3 code like:
statementOne;
statementTwo;
Is there any possibility that the garbage collector will run during or between my two statements, or does it only run after my "user" code has finished and returned control up to flash? We have an A-Star codeblock that's sometimes slow, and I'd like to eliminate the GC as a potential culprit. The codeblock is obviously more complex than my example above, but it doesn't involve any events or other asynchronous stuff.
I have ship game that i create using falsh as3. but i have the problem with memory usage. the memory usage still increase when game played. whereas the System.gc was called, but the memory still increase.
View 1 RepliesI am creating a bunch of movieclips when I first start the flash movie.I then put them into an array and use functions to add and remove them by selecting a random index in the array.When they are removed are they marked for garbage collection?Or can I just keep creating them.Might be hard to understand so code is below
var mc1:mov1 = new mov1();
var mc2:mov2 = mov2();
var mc3:mov3 = mov3();
var mc4:mov4 = mov4();
var theRandomClip:Number;
var movieClipArray = new Array(mc1,mc2,mc3,mc4)
function getRandom():void{
theRandomClip = Math.floor(Math.random()*movieClipArray.length);
addChild(movieClipArray[theRandomClip]);
}
function remove():void{
removeChild(theRandomClip);
}
//Then I would call them in succesion many times
getRandom();
remove();
getRandom();
remove();
//etc do I need to worry about them getting garbage collected and no
//longer being available?
Hope that makes sense
fully removing objects from memory, but I still think I'm not getting it. I've written a test script that looks the following:The stage has is of class MemTest
Code:

import flash.display.*
import flash.events.*

There is approximately a 3x difference in the rate of gain of memory usage between simply letting the movieclips accumulate or running removeChildforever() in the enterframe. There doesn't seem to be a difference between using the "killme = null;" line or not.However, I am still seeing an constant rate of increase in memory usage of about 3 megs over the course of a minute, running at 120 fps. why is the memory usage still going up? Is garbage collector run so infrequently that it hasn't happened after 7200 frames?
Lets say a scene started off around 70-80mb, it loaded a swf in, and by removing the event listener and setting objects to null and numbers to 0 before unloading the swf,and went back to the original scene, the memory stack up till like 80mb++, and every time I repeats the same process the memory goes up higher,is that normal? or its a memory leaking issue?
View 4 RepliesLooks like the garbage collector is not removing movieclips that have textfields set to TLF. I'm using Flash Builder's profile inspector and TLF brings in a bunch of objects and prevents the clip from being removed by the garbage collector (including all the objects that TLF put in memory). How could Adobe release CS5 with such a crappy implementation of text? If there is no solution I will have to avoid using TLF text for all my projects.
View 11 RepliesI've coded a 2000 line game on one actions layer (facepalm*) and I just recently learned about the GC (garbage collector). I've looked around a bit and can't, how to trace the source of it. There is an interesting article that mentioned event listeners and for every addEventListener there should be a removeEventListener. My game has 60 adds and only 15. What I can't make sense is that the mc's that have the event listeners are never removed, but just moved off of the stage. Others are just made invisible. So if the event listener is added once, why would the memory keep growing? (I'm using the Windows Task Manager to monitor this). Another point was to remove objects so that the GC can do its work. What I did was create an object, add it to an array then null it.
_object1 = new _barrel();
_object1.x = objectPosition;
_object1.y = _defaultFloorBoundary.y;
instanceArray[objectNumber] = _object1;
_object1 = null;
Then removed the object from the array.
for ( var ii:int = 0; ii<instanceArray.length - 1; ii++ ) {
stage.removeChild(instanceArray[ii]);
delete(instanceArray[ii]);
instanceArray[ii] = null;
}
I'm forgetting now exactly how I should dispose of unneeded objects. In the past, every object/class I created had a public dispose() function which removes all added listeners inside it and called the kill/dispose function on any children of it that may need the same (so it worked its way down the tree, as this process can continue for as many children/grandchildren there are in the list). So basically, the code in the parent class would look like this:
Code:
childObj.removeEventListener(MouseEvent.MOUSE_DOWN, anotherHandler);
childObj.dispose();
childObj = null;
...and the childObj class would look like this:
[Code] .....
Do I need to set any variables/objects defined in the child class's class scope to null prior to setting the class itself to null? Or is this handled automatically when I set the class itself to null from the parent (assuming these class-scope-defined variables/objects have no listeners or child objects which need to be disposed themselves)?
Is there any cross-platform-safe method for dealing with keyboard shortcuts in Flash? For example, on my Mac, pressing ctrl+f results in a KeyboardEvent where the keyCode is 6, but on Windows, the keyCode is 70.

I'm trying to handle movement of my Hero Class by adding event listeners in my constructor. I'm trying to move my Hero object.Inside my hero constructor, I have:
Code:
//Adding Event listeners
this.addEventListener(KeyboardEvent.KEY_UP, reportKeyUp);
this.addEventListener(KeyboardEvent.KEY_DOWN, reportKeyDown);
this.addEventListener(Event.ENTER_FRAME, EnterFrame);
And then I have functions for each of the events above. For some reason,the event listeners for key up and key down are never being triggered.
In flex, I am handling event like this,
myImage.addEventListener(MouseEvent.CLICK, redoOperation);
Now, I want to pass some value to redoOperation. (function redoOperation myId:String)) How can I pass String to it?
I want to have a single event listener for multiple events and depending on the type of event i want to handle them separately.Something similar to Swiz framework see: 'Handling Multiple Events from a Single Method'.i have a piece of code like
var toolOptions:UIComponent=ToolOptions.createToolOptions(type);
if (options != null)
{[code]....
In above toolOptions is a mxml component which get dynamically created based on 'type'.Also which type of event should be dispatch the event from the component? eg: Event.SELECT. To be more precise the above is basically required for a toolbar.When user selects a tool,he is shown options for a tool and when he selects options,tool should apply them to object on the view.
I need to do something and I don't know if it's possible... in a proper way.
1 - I have an FULLSCREEN application that extends to two monitors in a Windows system.
2 - The graphic card is extending the single desktop to the two monitors, so the fullscreen fits everything correctly.
3 - Only one monitor is interactivity-enabled, with an interactive touch-sensitive foil on it, which works great.
4 - The second monitor is interactivity-disabled, it just displays stuff depending on what happens on the first monitor.
The Problem: The interactive foil on the interactivity-enabled monitor responds as if it is the *whole monitor*. But it only covers one monitor!! The *whole monitor*, are the two screens put together. I obviously can't cut the interactive foil in 2, and then stretch the two parts to fill a monitor each... So if one touches beyond 50% of the foil's width, the touch event will actually occur in the second monitor!
A fact for the solution is - if all Mouse Events occur with mouseX divided by 2, everything will work fine! How to make all Mouse Events's mouseX be divided by 2? Is there a way to do that in the core of the actionscript MouseEvents handling?

I've decided to move on to AS3 (and maybe AS4 in the future). I've done PHP object oriented programming and Java oriented as well, but Flash is a bit different because of actual visual things that occur.
I tried to follow a very simple tutorial. I made a "collector" MovieClip and added both the identifier "collector" and the class "collector" to it. I added the project class as "superClass".
In superClass.as I had the following lines of code:
ActionScript Code:
package {
import flash.display.MovieClip;
import flash.display.Sprite;

is to an undefined method. I don't really see how this could be, since I have the collector class.

Yesterday when playing a game (Balloons Tower Defense 3) I noticed that the game started to slow down over time and then randomly speed up very quickly. Looking at the memory usage dropping each time I assumed it was the GC running.
As a legitimate question, is there anyway to force Flash to GC from, say, Firefox? Perhaps there's an addon or a command you can run that will do this? I know that you can do System.gc() but this game isn't mine so I can't modify the source with a "Click here to GC" button.
I've a question about garbage collection in flash.I'm making a game using with Flash AS3. This game will stay open for a few hours, like 5 - 6 hours. People will play it again and again in these hours. I have 15 loader in my flash game and don't want to have a problem with Garbage Collection. I'm uninstalling every load object when it is not necessary but i'm not sure do i have trouble about this garbage collection?
View 1 RepliesThis blog (and others) state that you should set object references to null inside your dispose() methods when cleaning up objects. However, Actionscript 3 (with Flash Player 9) uses mark and sweep to clear out circular references for you. So I am wondering: is there really any reason to null out your object references?

I have memory leak in my project and I wonder how garbage collector working in Flash Media Server.I have 2 questions: Will FMS release objects from memory that have cycle references. For example when object A is has ref to Object B and vise versa.Why FMS still consumes memory after application unloaded by idle timeout. For example there were no users connected then fms unloaded app after 20 minutes. Memory usage left at the same level (for a long period of time).

2. does anyone know how to force the flash to do garbage collection??
3. any other possible reasons that cause high cpu usage?
